This resource covers plant tissues like collenchyma and phyllode in Australian acacia, along with leaf arrangements. It also explores animal morphology, focusing on Periplaneta americana (cockroach) anatomy and the presence of elastin fibers. Additionally, topics such as dicot root vs. stem differences are discussed.
